* Move EthereumRpc implementation to Eth client

* Move SubstrateRpc implementation to SubstrateClient

* Update deploy_contract to use new RPC interface

* Fix some types in the Substrate client

* Swap out method bodies in Eth sync loop

* Swap out method bodies in Substrate sync loop

* Remove Client from SourceClient trait return types

* Remove Client from TargetClient trait return types

* Remove client from Source select! arms

* Remove client from Target select! arms

* Add missing mutable refs in Substrate client

* Use mutable references in Source/Target Client traits

* Try and use mutable references in Source/Client trait implementations

* Handle errors more gracefully

* Remove unused imports

* Remove dead_code and unused_variables lints

* Remove usage of `jsonrpsee::RawClient`

By using a `jsonrpsee::Client` we are able to remove all the shared
mutable references required when interacting with the RPC server. This
is convenient as trying to sharing mutable references in code that uses
async/await is a bit of a pain.

However, using a `Client` instead of a `RawClient` is not yet supported
by the `jsonrpsee::rpc_api` macro, so a fork must be used for the moment.

* Clean up dead code and warnings

* Clean up higher level RPCs

Some of the RPCs that were "high level" didn't necessarily belong
as part of the trait, so they were removed.

* Use positional parameters for RPCs

Both Substrate and Ethereum's RPCs use positional (array) parameters,
so in order to be compatible with both we need to make sure that
our API is defined with positional paramters in mind.

* Rename argument for eth_getBlockByNumber

* Remove some unecessary Ok-wraps

* Process client requests synchonously

Before the refactoring the sync loop would wait until a client finished
handling a request before issuing another one. This behaviour was
inadvertently changed during the refactoring leading to race conditions.
This commit makes sure that the previous behaviour is respected.

* Reduce the errors that are considered a connection error

* Only decode bridge contract once

* Set genesis_config at RPC client startup

* Fetch genesis hash in SubstrateRpcClient::new()

* Move Decode error into SubstrateNodeError

* Suppress warnings caused by `rpc_api!`

* Implement From RpcError for String

* Handle Substrate client initalization errors more gracefully

* Remove match in favour of ?

* Use async_trait for SourceClient

* Use aync_trait for TargetClient

* Revert async_trait usage for Source/Target client

This reverts commit f636ffaf.
This reverts commit 2c15755e

.

I'm having a very hard time finding out what is causing compilation
issues, and I think it's best to start over again.

* Use async_trait for TargetClient

* Use async_trait for SourceClient

* Move where non-async methods are

* RustFmt

* QueuedHeader holds Arc to actual data

* bump substrate

* cargo fmt --all

* Test defining an RPC API

* Add wrapper clients for the RPC API

* Implement most Ethereum RPCs

Does not include RPCs that require the bridge contract.

* Implement a few of the Substrate RPCs

Still missing proper error handling, as well as decoding responses from the
Substrate node.

* Make error handling more ergonomic

* Implement Substrate RPCs that use `state_call`

* Implement rest of Substrate RPCs

* Implement `eth_call` RPC

This can be used to implement higher level requests like fetching Substrate headers
from an Ethereum node.

* Build some of the higher level Ethereum RPCs

Uses the new Ethereum RPC interface to do so

* Build some of the higher level Substrate RPCs

* Remove old Ethereum RPC methods

* Remove old Substrate RPC methods

* Add some documentation to Substrate RPCs

* Fix typo in enum construction

* Revert commits `0f0435d2` to `ca755029`

This range of commits was mainly trying to integrate the new RPC interface into the existing
codebase, however this turned out to be a little out of scope for the current PR. Instead this work
will be incorporated into a PR which aims to close #72.

* Add documentation to RPCs

* Rename functions in RPC API to conform to snake_case

* Check that header contains a number and hash

* Put doc comments on trait instead of impl methods

* Remove expect() calls

* Replace runtime API enums with consts

* Accept Bytes when submitting extrinsic

Let's us avoid using a runtime specific Extrinsic.

* Add strictly typed arguments to RPC API

Missing two methods right now, which require a `serde::Deserialize`
implemenation before they can be changed.

* Add `chain_getBlock` Substrate RPC

* Use typed arguments for `eth_estimateGas` and `eth_call`

* Silence dead code warnings

* Add check for logs bloom

* Remove unused variables

* Add documentation to RPC error enums

* Use `CallRequest` type from rust-web3 crate

* Change CallRequest's `to` field to be optional

Required due to changes in upstream `rust-web3` crate.

* mute warnings from sub2sub module+relay

* cargo fmt --all

* Bump rust-web3 to latest master

* Use tagged release from crates.io

* Add check for `logs_bloom`

Since this is required by the runtime we want to enforce that an
incoming header has this.
